An unplanned release of liquefied petroleum gas during routine maintenance triggered a brief evacuation Tuesday morning at the Randolph Harley Power Plant on St. Thomas, the Virgin Islands Water and Power Authority announced in a press release.
WAPA confirmed the incident involved atmospheric venting of LPG through a designated vent while technicians were servicing the Wartsila Phase II units. Security personnel noticed a visible vapor plume in the venting area, prompting the immediate evacuation of the facility in line with safety protocols. The area was cleared and declared safe for reentry within 20 minutes, according to the press release.
Atmospheric venting is a standard practice conducted ahead of fuel line maintenance and occurs through pipes designed to mitigate risk. WAPA said the release was momentary and involved what is believed to be an insignificant volume of gas, the press release stated.
“There was no risk to the public, no injuries reported, and no disruption to electrical service,” the authority stated in a press release. “The venting area is specifically designed and permitted for such releases during maintenance operations,” the release continued.
WAPA added that it remains committed to reviewing procedures to ensure continued safety and reliability at its facilities.
